Paul Collier and Jan Willem Gunning analyze the slow economic growth and capital flight in Africa, attributing it to four key factors: limited openness to international trade, a high-risk environment, low social capital, and poor infrastructure. These issues are largely due to government behavior, as discussed in the political economy literature. The authors review aggregate-level and microeconomic evidence, finding a reasonable correspondence between the two, pointing to these four factors as important. They argue that the lack of social capital, particularly dysfunctional government, has reduced returns on investment, leading to capital flight. Social capital is improving, with some African governments liberalizing controls and improving service provision. However, the effects of these improvements on growth remain largely prospective. The paper also discusses the role of trade restrictions, deficient public services, and high aid dependence in slowing growth. It highlights the importance of financial depth, the impact of natural and policy volatility, and the role of social institutions in mitigating risks. The authors conclude that while some factors like geography and climate have contributed to Africa's growth challenges, the main issue is the lack of effective institutions and policies that support sustainable growth. The paper emphasizes the need for policy reforms to address these issues and improve economic performance.Paul Collier and Jan Willem Gunning analyze the slow economic growth and capital flight in Africa, attributing it to four key factors: limited openness to international trade, a high-risk environment, low social capital, and poor infrastructure.
